Tile Flooring Asymmetric Band Pattern Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tile type flooring experiences width deviations and defects during synchronizing cutting, leading to a monotonous appearance and instability, as the band pattern portions are cut on all four sides, causing uneven widths and expansion/contraction issues due to vinyl chloride resin characteristics.
Innovation Solution
The tile type flooring features band pattern portions formed on neighboring two sides of each main pattern portion, with a synchronized cutting method that reduces the total width of band patterns to half, and includes a size reinforcing layer and a multi-layer structure for enhanced stability and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If band pattern portions are formed at all four sides of main pattern portions, then the external appearance is enhanced, but the width deviation during cutting increases and manufacturing precision deteriorates
Solution Approach 1:
The patent applies asymmetry by forming band pattern portions at only two opposite sides of the main pattern portion rather than all four sides. This asymmetric configuration reduces the total number of cutting operations required, thereby minimizing cumulative width deviations and improving manufacturing precision while still achieving the desired aesthetic effect through strategic placement of band patterns.
2Shape
If the width of band pattern portions is reduced for natural connection, then the aesthetic appearance is improved, but the cutting precision requirements increase and manufacturing difficulty worsens
Solution Approach 1:
The patent extracts or removes the band pattern portions from three of the four sides, keeping them only on two opposite sides. This extraction approach naturally reduces the total width of band patterns to half, achieving the desired aesthetic appearance and natural connection effect while simultaneously reducing the cumulative cutting precision requirements and manufacturing difficulty.
3Manufacturing precision
If synchronizing cutting is performed on all four sides, then the pattern matching is achieved, but the vinyl chloride resin expansion and contraction causes defects
Solution Approach 1:
The patent extracts the cutting operations from three of the four sides, performing synchronizing cutting only on two opposite sides. This reduction in the number of cutting operations directly decreases the opportunities for defects caused by vinyl chloride resin expansion and contraction during heating and pressuring, thereby improving reliability while maintaining adequate pattern matching.
4Shape
If band pattern portions are formed at four sides to avoid monotony, then the external appearance is improved, but the total width of band patterns increases causing connection issues
Solution Approach 1:
The patent uses asymmetry by strategically placing band pattern portions on only two opposite sides rather than all four sides. This asymmetric arrangement achieves the desired aesthetic appearance to avoid monotony while reducing the total width of band patterns to half, thereby eliminating connection issues between tiles.

AI summary
A tile type flooring in which printing and cutting patterns coincide with each other, and a process for preparing the same. Band pattern portions (32) are respectively formed at neighboring two sides of each of main pattern portions (31) and synchronizing cutting is performed. Thereby, the total width of the band pattern portions (32) of each of tiles is uniformly narrowed. The tile type flooring has an aesthetic external appearance, and the tiles are naturally connected, thus expressing the reality of natural resources and the luxurious appearance. Further, if necessary, the flooring employs a size reinforcing layer (50) and has a transparent layer (20) and a first base layer (40), and a second base layer (60) and a balance layer (70), which are symmetrically stacked on the upper and lower surfaces of the size reinforcing layer (50), thus reducing defects caused by size instability of the flooring.
